Allen-Bradley 1756-IF16 Series A ControlLogix 16-Channel Analog Input Module (Voltage/Current)

The Allen-Bradley 1756-IF16 is a 16-channel analog input module for the ControlLogix 1756 I/O platform, accepting both voltage and current field signals. It provides 16 single-ended inputs, or 8 differential / 4 high-speed differential inputs when channels are wired in pairs, and supports voltage ranges of ±10V, 0–10V and 0–5V plus a 0–20 mA current range. A sigma-delta A/D converter delivers up to 16-bit resolution (15 bits plus sign on the bipolar ±10V range), with calibrated accuracy better than 0.05% of range on voltage inputs and 0.15% of range on current inputs; channel data is returned to the controller in IEEE 32-bit floating-point or integer format. Inputs are isolated from the backplane to 250V continuous (reinforced insulation), the module operates from 0 to 60°C, and it draws 2.33 W from the chassis. It is used across process and machine control to read 4–20 mA transmitters, sensors, and voltage-output field devices in a ControlLogix 1756 chassis.

This is a Series A hardware revision. ControlLogix analog modules occupy a single I/O slot and land field wiring through a removable terminal block — a 1756-TBCH (spring-clamp) or 1756-TBS6H (screw-clamp) RTB — which Rockwell does not include with the module as standard and which is required to wire the unit; confirm from the listing photographs whether one is supplied.

This unit is supplied in the condition shown and as listed. The photographs are of the actual item you'll receive, backed by our warranty.
