DESCRIPTION
The N2267A 8 Channel 8A General Purpose Module is designed for high-current (up to 8 A continuous), low-resistance switching applications, such as AC/DC power supply testing. It can also be used to switch on/off AC (up to 250 V) or DC (up to 125 V) power supplies and current sources. Each channel can carry 8 A of current at the same time. For thermal protection and reliability, the N2267A has a built-in temperature control circuitry that uses sensor ICs and a cooling fan. An over-temperature warning signal is also available to activate an external LED or buzzer. A protection network area is provided on the module's PCB, for switching inductive loads such as electric motors, solenoids, contacts, chokes, electromagnets and incandescent lamps. To protect relays from over-voltage damage, the RC network or the varistors must be placed on this module, which can effectively absorb the surge voltage. A connection terminal is not provided with the module. A crimp and insert connector (N2327A) is available for wiring use. The module is a plug-in for the 3499A/B/C Switch/Control System Mainframe (not included).
