Recently released, the Cephos C-TQ4 range of relay modules are a drop in replacement of the now obsolete Panasonic / Matsushita TQ4 and the Fujitsu RA4 four pole double throw, low voltage, low signal dil relays.
With an identical footprint the C-TQ4 relay module requires no pcb modification, fitted with gold finished pins it will fit existing 20 way dil pcb sockets or can be soldered directly into a printed circuit board.
The C-TQ4 relay module is available in a range of coil voltages: 4.5V, 5V, 12V and 24V currently stocked, others available on request. Single coil latching versions also available with 5V and 12V coil voltages.
