Installation and Wiring X-600M Users Manual
when connected to the X-600M. The X-600M would be able to support up to 16 modules under this
configuration (16 X 105mA = 1.68A). This example is workable because the expansion bus load current
is less than 1.70 Amps. For this example the power supply must be capable of providing 1.76A at
24VDC (80mA for the X-600M plus 1.68A for the devices on the expansion bus).
If only using a 12VDC power supply, each X-11s (2 relay expansion module) would use 196mA. The X-
600M would be able to support 8 modules under this configuration (8 x 196mA = 1.57A). This
configuration is workable because the expansion bus load current is less than 1.70 Amps. For this
example the power supply must be capable of providing 1.72A at 12VDC (150mA for the X-600M plus
1.57A for the devices on the expansion bus).
5-pin Connector
Pin Description
Vin+
9-28VDC (+) power supply input.
Caution: DO NOT EXCEED MAXIMUM POWER SUPPLY VOLTAGE.
Vin- Power supply (-) input. (Internally connected to the Gnd terminal)
Gnd Ground connection for 5VDC output
Data 1-Wire bus data connection for digital temperature and humidity sensors.
+5V Out
This output voltage is used to provide power for the 1-wire digital
temperature/humidity sensors.
2.3.3 System Start Up
At power-up, the green Power LED should be illuminated. The X-600M requires 10 to 15 seconds for the
operating system to load before it becomes operational.
2.3.4 Expansion Module Connections
Expansion modules are connected to the X-600M with a 10-conductor ribbon cable. Normally the X-
600M and the expansion modules are mounted side by side as shown in the photo below. The ribbon
cable connectors have a polarization lug to ensure correct connections.
