Honeywell Sensepoint XCD SPXCDALMTXT

Honeywell Sensepoint XCD SPXCDALMTXT

Specification

Use

3 wire, 4-20mA and RS485 MODBUS output fixed point detector with in-built alarm and fault relays for the protection of personnel and plant from flammable, toxic and Oxygen hazards. Incorporates a transmitter with local display and fully configurable via non-intrusive magnetic switch interface.

Electrical

Input Voltage Range

12 to 32VDC (24VDC nominal)

Max Power Consumption

Maximum power consumption is dependent on the type of gas sensor being used. Electrochemical cells = 3.7W, IR = 3.7W and catalytic = 4.9W. Maximum inrush current = 800mA at 24VDC

Current Output Relays

Sink or source 3 x 5A@250VAC. Selectable normally open or normally closed (switch) and energized/de-energised (programmable) Alarm relays default normally open/de-energized. Fault relay default normally open/energized

Communication

RS485, MODBUS RTU
