Nomenclature GT1-AD08MX TS indicator (status indicator of I/O Module interface) Indicates the status of the I/O Module Interface. PWR indicator (internal power supply indicator) The green indicator is lit when internal circuitry power supply is provided. U.ERR indicator (module error indicator) The red indicator is lit if the Module malfunctions or no internal circuitry power supply is provided. Connectors for I/O module interface Connects to the Communications Units or other I/O Mod- ules. Connect the Communications Module to connector 1. When connecting I/O Modules to the GT1-AD, connector 2 of the GT1-AD must be connected to +24VDC -24VDC connector 1 of the first I/O Module and connector 2 of the first I/O Module must be connected to connector 1 Specification Internal power of the next I/O Module. Connect all the I/O Modules in Setting supply terminals the same way. Switch Supply 24 VDC +10%/--15% to these Be sure to connect the end connector to connector 2 of terminals for the operation of the the last I/O Module. Module. TS Indicator (Status Indicator of I/O Module Interface) Voltage input COM Current input Green indicator lit The Module is normal. Analog input connectors 0 to 7 These connectors are for analog input use. Red indicator lit The I/O Module interface has an error. Each input connector has three pins (i.e., a pin for voltage input, COM, and current input from left to OFF No power is supplied to the Module or right) the Module is being initialized. 55
