High-Voltage Multiplexer Plug-In The Racal Instruments™ 1260-136 series plug-ins are high-voltage relay multiplexers for the Adapt-a-Switch™ platform. These quickly and easily plug into the front of an Adapt-a-Switch™ Carrier 1260-100 Product Information Each 1260-136 series plug-in can be con- figured via standard program control into any of the following configurations: • single 1x21 two-wire multiplexer • single 1x42 one-wire multiplexer • two 1x21 one-wire multiplexer 1260-136 plug-ins can be used for distribution applications in which any combination of relays per multiplexer are closed at a time, or in classical scanner applications in which only one relay per multiplexer may be closed. When used as a scanner, the 1260 series “exclude” feature will automati- cally open the last connection when a new connection is programmed. This reduces the number of commands sent to the switch, thereby reducing test time. Make- before-break or break-before-make can also be programmed. Three different versions of this plug-in are available to support a range of high voltage switching requirements. Each version uses a different high voltage relay. Basic “hot- switching” specifications of these plug-ins are as follows: • 1260-136B, 500 V, Reed Relay • 1260-136C, 1 kV, Reed Relay • 1260-136D, 500 V, Mercury Wetted Reed Relay The 1260-136D must be oriented vertically to operate properly. This is the normal position for installations using a 13-slot VXI chassis and Adapt-a-Switch™ carrier. The 1260-136B and C versions are not posi- tion sensitive; they will operate properly in installations oriented in any direction.
