1. Introduction
Module A-150 (Dual VCS) contains two separate
voltage-controlled switches.
Each switch has a control voltage input, a common
Out / Input, and two In / Outputs. The switches are
bi-directional: they can work in both directions, so
can connect one input to either of two outputs, or
either of two inputs to one output. Voltages in the
range -8V...+8V at the O/I resp. I/O sockets can be
processed by the module.
Two LEDs show which in / output is active (ie. which
is connected to the common out / input).
From about March 2004 a new version of the A-150 is
available. This allows the full A-100 voltage range
-12V...+12V for the voltages at the O/I resp. I/O soc-
kets. The new version can be identified at the pc
board label "A-100 SYSTEM A-150 DUAL VC
SWITCH VERSION 2
" near the bus connector at the
pc board edge.
