TM7SDI8DFS Wiring

Connection Elements

The following figure presents the connection elements for the TM7SDI8DFS:

Number	Meaning
1	TM5 link: 2 x M12 (4-pin) connector A: input connector B: output
2	Module supply 24 Vdc: 2 x M8 (4-pin) connector C: supply feed connector D: routing
3	Connectors 1 and 2: Digital I/O: 2 x M12 (8-pin)
4	Connectors 3 and 4: Digital I/O: 2 x M12 (5-pin)

Pin Assignments

The pin assignments of the power and communication connectors (A, B, C and D) are provided in the TM7 Physical Description.

Pin assignment for the 8-pin I/O connectors 1 and 2 of the TM7SDI8DFS module:

1 +24 Vdc

2 Test (pulse) output 1

3 COM

4 SI x (safety-related inputs)

5 DI x

6 Test (pulse) output 2

7 SI x (safety-related inputs)

8 DO x (non-safety-related outputs)

Connector socket	Pin1	Pin2	Pin3	Pin4	Pin5	Pin6	Pin7	Pin8
1 (IN/OUT)	+24 Vdc	Test (pulse) output 1	COM	SI 1	DI 1	Test (pulse) output 2	SI 2	DO 1
2 (IN/OUT)	+24 Vdc	Test (pulse) output 1	COM	SI 3	DI 2	Test (pulse) output 2	SI 4	DO 2

NOTE: Test (pulse) output 1 and test (pulse) 2 are shared between the connector sockets 1, 2, 3 and 4.

Pin assignment for the 5-pin I/O connectors 3 and 4 of the TM7SDI8DFS module:

1 Test (pulse) x

2 SI x (safety-related inputs)

3 COM

4 SI x (safety-related inputs)

5 Test (pulse) x (inputs)

Connector socket	Pin1	Pin2	Pin3	Pin4	Pin5
3 (IN)	Test (pulse) 1	SI 5	COM	SI 6	Test (pulse) 2
4 (IN)	Test (pulse) 1	SI 7	COM	SI 8	Test (pulse) 2

NOTE: Test (pulse) output 1 and test (pulse) 2 are shared between the connector sockets 1, 2, 3 and 4.

NOTE: Cross-circuits between the two channels of a connector cannot be ruled out according to ISO 13849-1. This is why shared error handling is implemented for both channels of a connector. This means that both channels are switched off as soon as an error has been detected on one channel.

Detected errors are acknowledged in a similar way. As soon as a detected channel error has been acknowledged, the error state on the other channel of the same connector is also acknowledged.

However, the restart inhibit is separately active for each channel to help prevent unintentional enabling of a channel.

WARNING
	IP67 NON-CONFORMANCE Properly fit all connectors with cables or sealing plugs and tighten for IP67 conformance according to the torque values as specified in this document. Do not connect or disconnect cables or sealing plugs in the presence of water or moisture. Failure to follow these instructions can result in death, serious injury, or equipment damage.
