        Description
        MURPHY C3-1A E6-K-0115 is a main I/O module used in the C3 Series Centurion Configurable Controller, a control and monitoring system developed for engine-driven compressors, pump systems, and other industrial automation applications. The module continuously monitors input signals and set points while commanding output devices to maintain stable system operation. Auto-start functions allow equipment to start or stop automatically according to pressure set points or digital control signals.

        MURPHY C3-1A E6-K-0115 integrates a wide range of I/O resources within a single module. It provides 32 optically isolated DC digital inputs, 12 analog inputs supporting 4–20 mA or 0–5 V signals with 10-bit hardware, 8 thermocouple inputs for Type J or Type K sensors with 12-bit hardware, and one magnetic pickup input operating from 30 Hz to 10 kHz with an input range of 5 VAC rms minimum to 120 VAC rms maximum. Open thermocouple detection and cold junction compensation improve measurement reliability for temperature monitoring applications.

        The module also offers flexible output capability through 10 digital outputs consisting of four Form C relay outputs with dry contacts, four FET source outputs, and two IGBT sink outputs. As the C3-1A version, MURPHY C3-1A E6-K-0115 includes two factory-installed analog outputs supporting both 4–20 mA and 0–20 mA signals with 16-bit hardware. Each analog output uses dedicated screw terminal connections, providing accurate analog signal transmission for industrial control systems.

        MURPHY C3-1A E6-K-0115 operates from a 10–32 VDC power input and supports an operating temperature range of -40 °C to 85 °C (-40 °F to 185 °F), allowing dependable performance in harsh industrial environments. All I/O functions are individually software selectable without hardware jumpers, simplifying configuration through the PC-based MConfigPro software. LED indicators provide clear status monitoring for digital inputs and outputs during operation.

        As part of the expandable C3 Series platform, MURPHY C3-1A E6-K-0115 can be augmented with the C3-2 expansion module to increase analog outputs as well as additional analog and thermocouple inputs. Real-time operating data can be communicated to HMIs, PLCs, PCs, and SCADA systems using industry-standard Modbus® protocol, making the module suitable for reciprocating compressors, screw compressors, pump systems, and other industrial process control applications.
