Compur Statox 4120

Construction:

The system consists of a 19“-4-HE rack with backplane and up to nine Statox 4120 control modules. Each Statox 4120 sensor head is communicating with one control module. The Statox 4120 rack is available in following designs:

STATOX 4120 Rack ½ x 19“ for 4 Control modules

STATOX 4120	Rack 19“ for 9 Control modules
STATOX 4120	Rack 19“ for 9 Control modules / RFI shielded
STATOX 4120	Desk case for	4 Control modules
STATOX 4120	Desk case for	19“ Rack with 9 Control modules

Connections:

On the backplane (pic. 3) you find the following terminals: power supply 230 V/AC (115V/AC)

Intrinsically safe terminals (signal cable, 22V/DC, 50mA) for data transmission and sensor head power supply.

Analog outputs:	0-1V
	4-20 mA
Potential free relays:	Pre-alarm A1
	Main alarm A2
	System alarm SF

The A1 and A2 relay signal of the Statox 4120 control module is programmable.
