• 4 input channels
• 0 to 20mA DC (0 to 20A AC with AC sensor) or ±10V DC input range
• 4 alarm channels, open drain MOSFETS (1A DC loads, 0 to 35V DC)
• 10 to 36V DC, 24V AC power
• 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.

• 4 analog output channels
• 0 to 20mA or 0 to 10V DC output range
• 4 discrete output channels, open drain MOSFETS (1A DC loads, 0 to 35V DC)
• 10 to 36V DC, 24V AC power
• Modbus RTU high-speed RS-485

These modules drive four analog output channels and also feature four discrete outputs for on/off control. Isolation separates the output, power, and network circuits. Network communication adheres to the industry-standard RS-485 Modbus RTU protocol.

• 4 input channels, thermocouple (types J, K, T, R, S, E, B, N) or millivolt (±100mV DC) input
• 4 alarm channels, open drain MOSFETS (1A DC loads, 0 to 35V DC)
• 10 to 36V DC, 24V AC power
• 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.  

• 2 or 4 input channels, RTD (100 ohm Pt, 120 ohm Ni, 10 ohm Cu) or resistance (0 to 500 ohms) input
• Solid-state relays discrete output, Form A, SPST-NO
• 10 to 36V DC, 24V AC power
• Modbus-RTU high-speed RS-485

This signal conditioner is a dual or quad-channel analog input module with one discrete/relay output per input channel and a Modbus interface. It filters and linearizes RTD or resistance inputs while providing isolation between input, output, power, and network circuits.

• 2 input channels, 0 to 50KHz in 3 selectable ranges: Amplitudes up to 140V AC peak, Amplitudes up to 200V peak, Pulse counter range of 0 to 65535
• Solid-state discrete output relays (1A DC loads), 0 to 48V DC
• 10 to 36V DC, 24V AC power
• Modbus-RTU high-speed RS-485

This signal conditioner is a two-channel analog input module with discrete outputs and Modbus communication. It conditions periodic or pulse waveform inputs and provides solid-state relays for limit alarms or ON/OFF control.
