- Identify 1746SC-CTR4 as Spectrum Controls hardware for an Allen-Bradley SLC 500 local chassis
- Match every channel to its DC counter or variable-reluctance AC flowmeter source
- Preserve the Class III slot definition, modes, filters, scaling and counter state before removal
1746SC-CTR4 is a Spectrum Controls four-channel slc 500 counter/flowmeter input module for the Spectrum Controls SLC 500 Specialty I/O platform.
Spectrum Controls 1746SC-CTR4 is a four-channel SLC 500 counter/flowmeter input module for DC pulse counting, variable-reluctance flow signals and quadrature encoder acquisition. 1746SC-CTR4 is manufactured by Spectrum Controls for the Allen-Bradley SLC 500 platform; it is not an Allen-Bradley-manufactured module and it is distinct from the eight-channel 1746SC-CTR8.
Before installation or replacement, verify the complete nameplate, compatible companion hardware, wiring or network design, saved configuration and commissioning plan.
Availability, condition, price, and shipping time for 1746SC-CTR4 are confirmed during quotation.
