Part Number: APR24-1-120B
This programmable Automotive Relay Panel (APR) is part of a range of software controlled relays which are easily programmed for a variety of applications including Battery Guard , Load Disconnect and Relay control . These relays provide an easy way to supply DC equipment in the range 3 -30V such as radios ,mobile phones ,in car entertainment systems ,fans heaters and computers. The unit draws less than 2mA in standby mode . The relay has additional inputs which can be configured to allow external control of the relay switching on & off, there is a status led & the option of remote indication (cab display) is included. The unit is supplied with standard settings but the Ablemail Software Interface (ASI) allows adjustment of connect voltage thresholds, timed relay on delays, voltage thresholds thresholds for load disconnect & timed relay off delays & specific customer requirements.
The serial interface as well as adjusting the settings can be used for controlling or being controlled by other Ablemail Electronics products which have a serial interface. This is useful in sophisticated Power Management Systems where multiple systems have to interact in real time. The unit can be configured to act as a temperature controlled relay and the standard serial interface can be replaced with an RS485 interface for use in electrically noisy environments or where parts are separated by more than 2-3m. The latest Euro 5 & Euro 6 engines have smart alternator & regenerative braking functions which the APR24 can monitor and take account of when operating the relay according to the system operation. This B variant is in an IP66 enclosure.
