TAC PNEUMODULAR � Multi-Input High and Low Selector
Relay
The selector relay is a device designed for use in
pneumatic control systems where the application
requires the comparison, selection, and
transmission of the highest and/or the lowest of up
to six pneumatic input signals. All input ports are
“dead-ended” and no signal air passes through the
relay to the output ports.
Features:
• Six-input high and low pressure selector. Requires main air
connection.
• Highest of 6 inputs is output at Port H.
• Lowest of 6 inputs is output at Port L.
• Inputs numbered 1 through 6.
• All ports clearly labeled. Ports align with MCS-S terminals.
• TAC PNEUMODULAR: Mounts on two MCS-Socket(s) or
on one K502 Mounting Bracket.
