Relay outputs for transistor output devices

The new RS-DIN rail relay system from Red Lion provides a compact and modular method of adding relay outputs to any transistor output device.

The new RS-DIN rail relay system from Red Lion provides a compact and modular method of adding relay outputs to any transistor output device.

The system is built around the relay block which is a terminal block that serves as a base for a miniature plug-in relay.

The relay block has a built in suppression circuit to reduce EMC interference, includes an input LED, offers reverse polarity protection and, at only 6.2mm wide, saves on DIN rail space.

The relay has a 24VDC coil, and its SPDT output can switch loads up to 250 VAC at 6 Amps.

With its plug-in design the relay can be replaced in seconds, thus saving considerable downtime.

An RSJMPR position jumper, with a maximum current capability of 6 A, is used to bridge connections between adjacent relay blocks.

This avoids the tedious task of wire-jumping signals such as commons or neutrals together.

An RSCJMP continuous jumper bridges up to 80 adjacent relay blocks with total currents up to 32 A.

Other parts of the system include a 9mm buss block and a barrier.

The buss block is the same shape as the relay block and is used as the starting point for the continuous jumper in applications which require up to 32 A.

For applications that require less than 6 A, the starting point can take place at one of the relay blocks.

The barrier should be used to isolate adjacent relay blocks with voltage potentials greater than 250V.

The barrier is equipped with prescored breakout points at the bridging positions, in order that individual bridges can pass through if needed.
