Detcon Model X40 is a low power alarm and control system designed to monitor multiple gas detection sensors and/or a wide range of other field devices. 

The versatile control system is designed to receive and supervise inputs using either 4-20 mA DC or Serial RS-485 Modbus™ and is available in two packages: Model X40-8 and Model X40-32. 

Both packages function as a Modbus™ Master and can be customized and expanded based on individual application needs using Detcon’s stackable din-rail mounted I/O modules. All I/O modules are individually addressable and operate on 11.5-30 Vdc. 

The X40-8 provides power for up to eight field devices and can house up to six 4-channel I/O modules. 

The X40-32 provides power for up to 32 field devices and can house up to 12 4-channel I/O modules. 

Detcon I/O modules available for use with the Model X40 include a 4-channel 4-20 mA input module (DA-4), a 4-alarm relay output module (RL-4), a 4-channel 4-20 mA output module (AO-4), and a 4-relay contact input module (DI-4). 

Detcon modules can be mounted within the main system enclosure or installed remotely to simplify field wiring. 

The Model X40 is completely field programmable using a small handheld magnet and offers advanced technology with intuitive, embedded intelligence. 

The control system displays real time readings and field device status on a backlit LCD screen. 

During normal operation the screen displays the alarm status and current reading (i.e., channel number, gas type, and gas concentration) for up to 8 field devices simultaneously. The display is sequential and during normal operation it auto cycles through each of the active channel screens. 

Among the system’s unique features is a wireless option that can be used with Detcon’s RXT-320 SmartWireless® transceivers. 

Enclosure options include: NEMA 4X, NEMA 1 panel mount, and NEMA 7.
