DC Current Input Module with Limit Alarms
INPUT: 4 channels, 0 to 20mA DC input range (0 to 20A AC with AC sensor option)
ALARMS: 4 channels, open drain MOSFETS (1A DC loads, 0 to 35V DC)
POWER: 10 to 36V DC, 24V AC
NETWORK COMMUNICATION: Modbus RTU high-speed RS-485

This signal conditioner is a four-channel analog input module with four discrete outputs. It provides isolation between input, output, power, and network circuits. Network communication adheres to the industry-standard RS-485 Modbus RTU protocol. AC and DC power sources are supported with nonpolarized, diode-coupled terminals.


The inputs accommodate wide DC voltage or current ranges. Flexible discrete outputs operate as alarms or on/off controllers. As limit alarms, each discrete output can be configured with high and/or low setpoints exclusively tied to an analog input channel. Alarm trips function without host communication enabling low-cost stand-alone alarms, as well as local backup for the primary control system. Otherwise, on/off control is based on commands issued by the host system.

Combining flexible transmitter functions, mixed signal I/O, alarm support, and a network interface in a single package, makes this instrument extremely powerful. Multi-channel design adds cost-efficiency and allows high-density mounting. Plus, safe, rugged construction makes these modules reliable for use in both control room and distributed field I/O applications.

Thermocouple/Millivolt Input Module with Limit Alarms
INPUT: 4 channels, thermocouple (types J, K, T, R, S, E, B, N) or millivolt (±100mV DC) input
ALARMS: 4 channels, open drain MOSFETS (1A DC loads, 0 to 35V DC)
POWER: 10 to 36V DC, 24V AC
NETWORK COMMUNICATION: Modbus-RTU high-speed RS-485

This signal conditioner is a four-channel analog input module with four discrete outputs. It filters and linearizes thermocouple inputs while providing isolation between input, output, power, and network circuits. Cold junction compensation and upscale/downscale sensor break detection are standard. AC and DC power sources are supported with nonpolarized, diode-coupled terminals.


The programmable inputs accommodate eight thermocouple types plus wide-range millivolt signals. Flexible discrete outputs operate as alarms or on/off controllers. As limit alarms, each discrete output can be configured with high and/or low setpoints exclusively tied to an analog input channel. Alarm trips function without host communication enabling low-cost stand-alone alarms as well as local backup for the primary control system.
