Single Channel Controllers

Model 4001

Model 4011

Model 4001 and 4011 Single Channel Controllers interface with industry standard two- or three-wire 4-20 mA sensor transmitters and provide the user with concentration display and two independent adjustable alarm levels.

The Model 4001 and Model 4011 Single Channel Control- lers are single channel gas detection controllers that also can be used with most industry standard 4-20 mA or other standard voltage/current sensor transmitters. Both con- trollers provide the user with two independent adjustable alarm levels. In addition, the output can be continuously sent to a chart recorder.

The alarm relays can be programmed to be either latching or non-latching and to activate either as a rising or falling alarm. When the controller is used with 4-20 mA sensors, a third alarm provides a fault indication when the controller detects loop current less than 3 mA. The alarms are ac- knowledged via either an external reset switch or a reset push-button on the Model 4011

Each alarm relay is fused to prevent damage from alarm and control circuits. The relays are SPDT Form C type rated at 5 Amps to provide direct alarm action, reducing the need for interposing relays.

Model 4001

The Model 4001 is housed in a NEMA 4X wall mount en- closure or the optional NEMA 7 explosion proof enclosure. AC or DC powered versions are available. Both versions include as standard an integral battery charger that can provide a trickle charge to an optional battery to provide reliable continuous service.

Model 4001

Model 4011

The 3 1/2 digit LCD display can read the concentration or alarm setpoints. LEDs on the front panel provide indication of all three alarms or low battery power.

Model 4011

The Model 4011 is in a 1/8 DIN panel mount enclosure. This controller is DC powered. Optional power supply/ battery chargers can power to a single unit or up to 4 con- trollers.

The front panel includes a 3 1/2 digit LCD display, LEDs indicating the three alarms, reset push-button, four dis- play selection LEDs and a Select Pushbutton. The RE- SET button is used to reset the relays when the user has selected Latching or Acknowledge mode. The SELECT button steps the display through each of the four possible selections that will be indicated by the appropriate illumi- nated LED.
