Manufacturer: Rockwell Automation
Brand: Alan Bradley
Part Number/Catalog number: 1756-OF8IHK series
Series: ControlLogix
Module type: ControlLogix HART I/O module
Channels: 8 isolated differential outputs and 1 HART modem per channel
The Allen-Bradley 1756-OF8IHK is a ControlLogix HART I/O module. The module is tested for its durability against ASTM B845-97 Method G Accelerated test environment (20 days exposure) and IEC 60068-2-60 Test Method 2 Accelerated test environment (20 days exposure). The 1756-OF8IHK is supported by DTM and C-UL-US, CE, RCM, Ex, KC, EAC certifications.
The 1756-OF8IHK operates at DC input voltage and is rated +/ -24 V DC with overvoltage protection. In addition, it can operate at 250V AC isolation voltage and at a rate of 15% at 4-20A. It has 15 bits with a 24 Miliamperes resolution rating and 8 isolated differential outputs, 1 HART modem per channel, module HART scan time of 1 second and support for HART (estimates). Current input ranges from 0-20 mA and 4-20 mA. It is also compatible with HART 6 and 7.
The 1756-OF8IHK has an open housing type with conformal coating. The conformal coating analog output HART isolation current is 8 Pts (36 pins).
Allen-Bradley 1756-OF8IHK ControlLogix HART I/O module provides chassis based modules that support a wide range of digital, diagnostic digital, analog, motion control, and dedicated I/O to meet all application needs. The 1756-OF8IHK can be used with any I/O module in the local chassis of the ControlLogix controller, or any I/O module in the chassis connected to the ControlLogix controller via ControlNet or an EtherNet/IP network.
The 1756-OF8IHK requires either a detachable terminal or a Bulletin 1492 wiring interface module to connect all field side wiring.
