Allen-Bradley|1756-CFM|Configurable Flowmeter Module
Allen-Bradley 1756-CFM Configurable Flowmeter Module
Description
The Allen-Bradley 1756-CFM is a ControlLogix configurable flowmeter module designed for precise flow, totalizer, and prover applications with dual-channel inputs and current-sourcing outputs.
Features
Supports flowmeter and totalizer modes.
Compatible with magnetic pickups and powered preamp outputs.
Removable terminal blocks for easy wiring.
Technical Specifications
Operating Temperature: 0 °C to 60 °C (32 °F to 140 °F)
Input Voltage Range: ±30 V peak; selectable thresholds at 50 mV, 1.3 V, and 4 V
Logic Levels: >1.3 V DC = Logic 1; <0.7 V DC = Logic 0
Output Voltage Range: 4.5–5.5 V DC (5 V mode); 10–31.2 V DC (12/24 V mode)
Backplane Current Draw: 300 mA at 5.1 V; 25 mA at 24 V
Total Power Dissipation: 3.12 W maximum at 60 °C
Thermal Dissipation: 10.6 BTU/hr
Isolation Voltage: 250 V continuous (reinforced insulation, I/O-to-backplane); 250 V (basic insulation, group-to-group)
Inputs: 4 total (2 per channel)—flowmeter and gate inputs
Outputs: 2 current-sourcing
Terminal Blocks: 1756-TBNH or 1756-TBSH
Wire Size: 0.25–2.5 mm² (22–14 AWG), shielded copper, 75 °C rating
