Allen-Bradley 1756-OF8H A ControlLogix HART Analog Output Module

The Allen-Bradley 1756-OF8H is an eight-channel ControlLogix analog output module with a built-in HART modem, designed for direct control of HART-enabled field devices in a ControlLogix I/O chassis. Each channel can be configured for voltage or current output, with an output range of ±10 V or 0–20 mA (4–20 mA option) and a 15–16 bit resolution across all ranges; there is one HART modem per module to communicate with HART devices. The module supports standard backplane power for 1756 I/O, with a total backplane power of 6.54 W and isolation between the output channels and the backplane rated at 50 V.
