Safety Expansion Relay
INT-05-024
INT-05-120 INT-05
TUV Notes:
1. Relay conforms to Pollution Degree II, meets EN1760-1:1998, and must be installed
in an IP54-type enclosure.
2. The wire insulation of connected devices must be rated for 250VAC. The relay meets
basic insulation requirements only.
3. Input devices must meet requirements of EN60947-5-1.
4. The relay must be connected to a primary disconnect device that meets the
requirements of EN60947-3.
5. Controller meets IP20.
6. Test system before operation and after machine maintenance. Controller does not
require maintenance.
7. The complete system should be tested weekly. If a fault occurs, contact
Sentrol Industrial.
8. To be used in conjunction with INT-03 or INT-04.
The INT-05-024 or INT-05-120 Expansion Safety Relay is intended for use as part of a
safety circuit. It provides three additional safe output contacts when used with the
INT-03 Safety Monitor Relay or INT-04 Emergency-Stop Safety Relay.
The INT-05 uses positive-guided relays along with feedback contacts to the INT-03 or
INT-04 safety relay to prevent machine start-up in the event of a component failure.
Voltage to the INT-05 is switched thru the contacts of the INT-03 or INT-04. If a
component failure occurs, the feedback loop to the
INT-03 or INT-04 prevents machine restart.
Description
Installation
1. Mount the relay on a 35mm DIN rail or panel. See Dimensions.
2. Connect the wiring for the switches and relay. See Wiring Diagrams. (For proper
operation, DO NOT jumper terminal 1 to terminal 2. Use a momentary button.) For
floor mat applications, connect the two floor mat loops from terminal X1 to X2 and
from Y1 to Y2.
Caution! The relay is available in either a 24 VDC, 120 VAC, or 230 VAC model.
Make sure correct model is used before
applying power.
3. Use one of the following methods to energize the relay:
• For E-stop installations, close all E-stop button contacts and monitored contacts,
and then press the START button.
• For floor mat installations, press the START button without an object on the mat.
Note: The INT-05 must be wired as shown as the unit on its own does not fulfill any
safety requirements.
