Keysight N2264A multifunction module combines 12 general purpose relays, three high current relays, and a 16-bit digital input/output in one module. The N2264A is designed for applications that require multiple functions in one module for space saving and system cost saving. A screw terminal block, crimp and insert terminal block, and DIN96-to-D25/D50 cables are available for ease of wiring.

The 16 I/O bits can be addressed individually (bit-by-bit), or as two independent 8-bit ports, or as one 16-bit port. A Zener diode is used in each channel for input voltage over protection (>42V DC), and ESD protection. Each I/O line can sink up to 0.6 A to control external devices.
