Detailed information on wiring, configuring, and operating
an MSR57P relay, including safety requirements.
Retain these instructions for future reference. Rockwell Automation cannot accept
responsibility or liability for a failure of this device if the product is used outside the
recommended specifications in this document.
ATTENTION
This device is intended to be part of the safety-related control system of a machine. Before
installation, a risk assessment should be performed to determine whether the specifications
of this device are suitable for all foreseeable operational and environmental characteristics
for the machine to which it is to be fitted. At regular intervals during the life of the machine,
check whether the characteristics foreseen remain valid.
ATTENTION
Safety Programmable Electronic Systems (PES)
Personnel responsible for the installation and application of safety-related programmable
electronic systems (PES) shall be aware of the safety requirements in the application of the
system and shall be trained in using the system.
Spacing Requirements
Adequate air space must be provided around the system (module cluster). Minimum
recommended clearances:
• 15 mm (0.6 in.) above
• 15 mm (0.6 in.) below
• 2…3 mm (0.08…0.12 in.) between modules at ambient temperatures higher
than 40 °C (104 °F).
Mount the MSR57P Relay
Follow these steps to mount the MSR57P relay to an EN50022 -35 x 7.5 DIN rail.
1. Hook the top slot over the DIN
rail.
2. Snap the bottom of the device
into position while pressing the
device down against the top of
the rail.
3. Attach end plates on each end
of the DIN rail.
To remove the device from the DIN rail,
use a flathead screwdriver to pull down
the latch and lift the device from the rail.

This example is configured for Safe
Stop 1. The control cabinet
contains an MSR57P relay, a
PowerFlex 70 AC Drive with
Safe-Off function, as well as a
PanelView terminal. The MSR57P
relay monitors speed via a TTL
encoder connected to the
PowerFlex 70 drive.
The control panel lets the operator
select Run or Maintenance speeds.
The door has an interlock switch
with guardlocking to limit access
to the machine when the machine
is operating at normal Run speed.

In addition, an enabling switch is
required to be held in the middle
position while operators are within
the machine environment to keep
the machine running at safe speed.
