Features:
- Collects fourteen Pt100, Pt1000, type J, or type K temperature inputs.
- Offers two-wire and three-wire RTD evaluation with lead compensation.
- Combines cable-break detection, signal averaging, and 500 V system isolation.
TI214 lets each input channel use the sensor technology suited to its measuring point instead of forcing one module-wide selection.
Selectable averaging and low-pass filtering help separate stable process temperature from electrical interference.
The internal Pt100 reference can represent cabinet temperature for thermocouple cold-junction compensation without an added channel.
The Bachmann TI214 M200 Temperature Input Module is covered by a current Bachmann product datasheet and may be available from Apter Power.

Flexible sensor assignment
- Channel Choice: Each of the fourteen measuring points can be assigned independently to a supported sensor type.
- RTD Inputs: Pt100 and Pt1000 elements cover measurements from -100 to +800 degrees Celsius.
- Thermocouples: Type J or K inputs cover the -30 to +1000 degrees Celsius range.
- Lead Arrangement: Resistance sensors may use either simple two-wire wiring or compensated three-wire wiring.
Stable measured-value handling
- Conversion: Fourteen-bit measurement is presented in a 16-bit averaged value.
- Averaging: The controller can select 16-fold or 64-fold averaging to suppress interference.
- Input Filtering: A per-channel first-order low-pass filter shapes the incoming temperature signal.
- Open-Circuit Check: Cable-break recognition distinguishes a missing sensor path from a valid temperature value.
Electrical operating boundary
- External Supply: The module accepts 18 to 34 VDC and draws about 160 mA at 24 VDC.
- Supply Supervision: External-voltage monitoring reports whether the measurement electronics are being powered.
- Polarity Protection: Reverse connection of the supply is blocked by the module's input protection.
- System Separation: A 500 V galvanic barrier isolates the temperature channels from the controller system.
Supported temperature-measurement roles
- Cabinet Reference: The integrated Pt100 element can measure switching-cabinet temperature on the same module.
- Thermocouple Control: Type J and K channels suit temperature-control systems built around thermocouple sensors.
- Long RTD Runs: Three-wire evaluation compensates equal lead resistance in symmetrical Pt100 or Pt1000 cables.
- Mixed Measurement: Independent channel selection combines resistance sensors and thermocouples within one compact station.
