VCL-TP-1531-PMX, Protection Relay I/O Multiplexer

Get Data Sheet

VCL-TP-1531-PMX, is designed to multiply the Binary Output Commands of a Sub-station Protection Relay to connect additional devices such as Teleprotection Equipment, Circuit Breakers, Bay-Control Units etc.

The VCL-TP-1531-PMX provides up to 4 x Binary Command Inputs and up to 16 x Binary Command Outputs in which any input can be mapped to any output / or multiple outputs. All inputs have individually programmable glitch filters (command rejection) ranging from 0.5ms to 5ms to reject spurious input commands. All outputs have individually programmable pulse-widths ranging from 0.5ms to 1000ms, which may be programmed by the user on a per channel basis to ensure complete customization to meet diverse sub-station requirements. The VCL-TP-1531-PMX is a ruggedized, sub-station hardened, industrial grade unit which makes it suitable for installation in critical infrastructures like oil, gas or electric utilities.
