Signal Repeating Relay
Model Chart
Specifications
The signal repeating relay is a proportioning device
for use in pneumatic control systems where it is
desirable to repeat a pneumatic signal accurately,
such as the output signal from a pneumatic
transmitter which must be transmitted to receiver
controllers or indicators at multiple locations. In
addition to accurately repeating the input signal,
use of the relay minimizes transmission lag by
increasing the volume of signal air to devices
located remotely from transmitter (see Figure 1).
This device may also be used as a signal blocking
relay and as a signal limiting relay.
Features:
• Signal-repeating relay; repeats transmitter signal to
multiple pneumatic devices at remote locations. No
adjustments.
• May be used for signal-blocking applications.
• May be used with two adjustable restrictors as High/Low
Signal-Limiting Relay.
• All ports clearly labeled. Ports align with MCS-S terminals.
• TAC PNEUMODULAR: Mounts on MCS-S Socket or K502
Mounting Bracket.

Operation
Signal repeating application Restricted main air at port B will accurately track the input pressure at port S.
Blocking application
With no air pressure applied at port S, ports V and B are connected. With air pressure at port S, ports
V and B are blocked.
Construction Glass-filled nylon.
Maximum ambient temperature 140qF (60qC).
Supply air pressure Clean, dry, oil free air required (Ref. EN-123).
Nominal 20 psig (138 kPa).
Maximum 30 psig (207 kPa).
Connections Barbed fittings for 1/4 in. O.D. polyethylene or 5/32 in. I.D. polyurethane tubing.
Air consumption 1728 scim (7.9 mL/s).
Air flow capacity 1728 scim (7.9 mL/s).
Adjustments None.
Mounting
Designed for use on MCS-S manifold socket. This device can also be mounted by using the K502
mounting bracket.
