Logic elements
A range of logic elements suitable for mounting on 3 port subbase.
The subbases have 4mm push in fittings, a clip for DIN rail mounting and are availble in two versions - "Cascade" or "Common" - see previous section for description.
Subbases can be used standalone or joined together in an assembly.
An input module (optional) can be used at the start of a block.
Approximate switching pressures (80 psi supply):
NOT (standard) 50psi on rising, 15psi on falling
NOT (threshold) 60psi on rising, 1/12 supply on falling
YES 40psi on rising, 20psi on falling
Memory
The purpose of the memory relay is to maintain an output after the set signal has been removed.
Available with and without a manual override the memory relay must be used with the 4 port subbase.
Time delay relays can also be built into this system (see next section).
