Alternating Relay Function – Worth Keeping in Mind

A genuinely useful feature for balanced equipment operation and longer service life.

📅 Published by PCSPL ⏱ 6 min read 🏷 Process Control
Recently, we introduced an alternating relay function to selected SIMEX process meters. If it slipped past you at the time, no stress — here’s a quick recap of why it’s a genuinely useful feature.

What the Alternating Relay Function Does

This function enables automatic switching between relay outputs, ensuring pumps, fans, compressors, and other actuators share the workload evenly. The result is smoother operation, reduced wear, and longer service life across your equipment.


What This Means in Practice

No additional controllers required
No manual switching or operator intervention
Alternation handled directly inside the meter
Improved system reliability and balanced equipment usage

SIMEX Meters with Alternating Relay Function

The alternating relay function is available in the following SIMEX models:

SRP‑94
SRP‑946
SRP‑N118
SUR‑457

Including configurations with 3× relay outputs + 1× analog output, giving you flexibility for more complex control schemes.


A Practical Application

Imagine a pair of air‑conditioning compressors. Instead of one unit doing all the work while the other sits idle, the meter automatically alternates between them — delivering fair workload distribution, balanced wear, and longer equipment life without any extra hardware.
