Overview Manuals Specifications

Features:

  • Twelve isolated thermocouple input channels for PACSystems RX3i
  • Supports J, K, T, E, R, S, B, N, C thermocouples and voltage inputs
  • Cold junction compensation with per-channel diagnostics and alarms
The IC695ALG312 provides essential temperature sensing functions critical to the entire control path, serving as the primary interface between thermocouple sensors and the control system, directly affecting the proper, normal operation of the overall automation system.

For applications requiring maximum accuracy, the IC695ALG312 supports cold junction compensation using up to two external CJC sensors (IC695ACC600) that mount directly on the terminal block. In addition to standard signal conversion, the CJC temperatures on the IC695ALG312 are reported as separate channels in the input data, with the module automatically using this information to compensate for offset voltages at the thermocouple connection point.

The IC695ALG312's robust design ensures reliable operation in industrial environments. Using high-quality components with per-channel isolation, the module delivers precise measurements with voltage accuracy of ±0.1% of span at 25°C. The comprehensive diagnostic capabilities of the IC695ALG312 include per-channel detection of under range, over range, open wire, rate of change, and configurable high, high-high, low, and low-low alarms with programmable deadbands.

The IC695ALG312 General Electric INPUT MODULE may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Model IC695ALG312 is a precision isolated thermocouple input module engineered for the PACSystems RX3i platform, providing twelve fully isolated differential input channels for temperature measurement applications. This module requires an RX3i Universal Backplane and a CPU with firmware version 6.5 or later, along with PAC Machine Edition Version 6.5 or higher for configuration. 

Configuration flexibility is a hallmark of the IC695ALG312, with all parameters completely software-configurable without requiring module jumpers. Each channel on the IC695ALG312 can be independently set for thermocouple type, temperature units (Celsius or Fahrenheit), and data format (32-bit floating point or 16-bit integer). 

Diagnostic and alarm capabilities on the IC695ALG312 are comprehensive and user-configurable. The module provides per-channel detection of under range, over range, open wire, and rate of change conditions, along with configurable high, high-high, low, and low-low alarms with programmable deadbands. The IC695ALG312 features module fault status reporting including watchdog, RAM fail, and flash fail conditions, along with complete module identity and status reporting via LED indicators. 

The IC695ALG312 utilizes separately ordered terminal blocks including box-style (IC694TBB032, IC694TBB132) or spring-style (IC694TBS032, IC694TBS132) options, with extended versions providing additional shroud depth for shielded wiring. Accuracy specifications for the IC695ALG312 are impressive, with voltage accuracy of ±0.1% of span at 25°C and ±0.25% over temperature range.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What thermocouple types and temperature ranges are supported by the IC695ALG312 module?
The IC695ALG312 supports nine thermocouple types including J, K, T, E, R, S, B, N, and C, covering temperature ranges from -270°C to +2315°C depending on type. Specific ranges include Type B (+300 to +1820°C), Type C (0 to +2315°C), Type E (-270 to +1000°C), Type J (-210 to +1200°C), Type K (-250 to +1372°C), Type N (-210 to +1300°C), Type R (0 to +1768°C), Type S (0 to +1768°C), and Type T (-270 to +400°C). The IC695ALG312 also supports ±50mV and ±150mV voltage inputs.
How does cold junction compensation work on the IC695ALG312?
The IC695ALG312 supports cold junction compensation using up to two external CJC sensors (IC695ACC600 sold separately) that mount directly on the terminal block. CJC temperatures are reported as separate channels in the input data, with measurement resolution of 0.01°C and typical accuracy of ±1.5°C over 0-60°C range. The CJC update rate on the IC695ALG312 is fixed at 20 Hz with a 4.7 Hz filter, and CJC scanning must be enabled in the module configuration to use cold junction compensation.
What filter options and diagnostic capabilities are available on the IC695ALG312?
The IC695ALG312 features programmable notch filters with selectable frequencies of 2.3 Hz, 4 Hz, 4.7 Hz, 24 Hz, and 28 Hz, allowing optimization for noise rejection versus response time. Diagnostic capabilities include per-channel detection of under range, over range, open wire, positive and negative rate of change, and configurable high, high-high, low, and low-low alarms with programmable deadbands. The IC695ALG312 also provides module fault status reporting for watchdog, RAM fail, and flash fail conditions.
What are the system requirements for using the IC695ALG312?
The IC695ALG312 requires an RX3i Universal Backplane with PCI bus support and an external isolated +24 VDC power source connected via the TB1 connector. The module requires an RX3i CPU with firmware version 6.5 or later and PAC Machine Edition Logic Developer-PLC Version 6.5 or higher for configuration. The IC695ALG312 uses separately ordered terminal blocks (IC694TBB032, IC694TBB132, IC694TBS032, or IC694TBS132) and supports CJC sensors ordered as IC695ACC600.
