4.5 Using Digital I/O on eMB-40M XIO Connector NOTE: The input current specifications are provided for reference. Voltage sources are typically used to drive the inputs. Typical Input Wiring Example A M N O H 1097 S1 1098 S2 1099 S3 C 1100 S4 B1 1101 P1 1102 XIO – DB-Sub 26 F D1 +24V G 1103 1104 1105 C 1106 B2 1107 P2 1108 D2 G +24V Figure 4-5. Typical User Wiring for XIO Input Signals NOTE: The off-state current range exceeds the leakage current of XIO outputs. This guarantees that the inputs will not be turned on by the leakage current from the outputs. This is useful in situations where the outputs are looped-back to the inputs for monitoring purposes.
