HP E2272A Dual 8-to-1 Relay Multiplexer M-Module


 [ Summary ][ Features ][ Specifications ][ Ordering ][ Assistance ]

Product Summary

The HP E2272A Dual 8-to-1 Relay Multiplexer is a single- wide, register-based M-Module. Use the HP E2272A as an input or output multiplexer for a matrix or other switching configuration.

It consists of 16 DPST latching relays and is organized as two separate 8-to-1 relay multiplexers. This allows the selection of 1-of-8 two-wire signals to connect to one common destination while the other set of 8 two-wire signals can be selectively connected to a second destination. By moving a jumper on the module, you can configure the HP E2272A as one 16-to-1 multiplexer.

With each M-Module having its own address within the HP E2251A M-Module carrier, you have the flexibility to use the M-Modules in many combinations. This flexibility allows you to get the amount of functionality you need in smaller blocks, lowering your overall system costs. For cabling access, only 5 HP E2272A M-Modules can be placed in one HP E2251A. Please see the HP E2251A for further M-Module slot requirements.
