Allen Bradley ControlLogix HART Analog I/O Modules 1756-IF8IH With Good Price In Stock

The ControlLogix HART analog I/O modules have built-in HART modems, so there is no need to install external HART multiplexers or clip-on HART modems. The 1756-IF8H and 1756-OF8H modules have one HART modem per module. The 1756-IF8IH, 1756-IF16H, 1756-IF16IH, and 1756-OF8IH modules have a separate HART modem for each channel.

The 1756-IF8IH functions as a HART master. It communicates with HART devices that have a HART revision of 5, 6, or 7. Each channel has its own HART modem and functions as a HART primary master.The 1756-IF8IH module supports one HART device per channel.The 1756-IF8IH module does not support burst mode, phase shift keying (PSK), or multi-drop network configuration. The module detects and turns off a bursting device at initial connection with the 

device.

The 1756-IF8IH module is an isolated, 8-channel, current-only input module capable of HART communication on all channels. Each channel is individually configurable. 

The 1756-IF8IH module has the following features: 

• Eight isolated, individually configurable input channels with a separate HART modem on each channel 

• Channel-to-channel, channel-to-backplane, and channel-to-frame ground galvanic isolation at a continuous level of 250V AC rms

• Two input ranges: 0...20 mA and 4...20 mA 

• Choice of four data formats: 

• Analog Only 

• Analog and HART PV 

• Analog and HART by channel with Configure HART Device = No 

• Analog and HART by channel with Configure HART Device = Yes 

• Supports full simultaneous HART 1200 baud bandwidth to all channels 

• Channel ADC filter (one setting per module) 

• Digital filtering (configurable per channel) 

• Real-time sampling 

• Auto-scanning of HART variables (PV, SV, TV, FV) 

• HART pass-through interface 

• Option to configure a HART device with user-supplied data. You can configure PV damping value, PV range values, PV transfer function, and PV units code. This option is available only when the data format is Analog and HART by Channel with Configure HART device = Yes 

• User scaling of input data
