Description
The MSR22LM safety monitoring relay is designed to monitor light curtains with the added features of muting and presence sensing device initiation (PSDI). It provides an output to a machine control system when the light curtain is clear. When the inputs to the MSR22LM are closed (conducting), the output relays are closed if the monitoring circuit is satisfied.
The MSR22LM has three sets of dual channel inputs. This allows it to operate in four different configurations:
| 1. | Monitors up to three light curtains in guard only mode. |
| 2. | Monitors up to two light curtains with two muting sensors (only one curtain muted). |
| 3. | Monitor one light curtain with four muting sensors. |
| 4. | Monitors up to three light curtains with PSDI (only one curtain initiated). |
The MSR22LM uses microprocessor based technology to offer a wide variety of advanced safety solutions in a small 45 mm DIN rail mounted housing. Internal selector switches provide for easy selection of up to ten different applications. Four LEDs give operational status as well as diagnostic information. Removable terminals reduce wiring and installation costs when replacement is necessary.
