6.1.2 MTL4510 & MTL4510B - Switch/Proximity detector interface
4-channel digital input and multifunction modules
These digital modules provide solid state output switches in a safe area that respond to switches (inputs)
located in a hazardous area. The way they respond - their “mode” - can be configured using a bank of
four DIL selector switches accessible through the side of the module - see Figure 6.2.
Model MTL4510 has an one output channel for each input channel and the user can reverse the output
phase if necessary to suit the application. Model MTL4510B has more varied modes that can, for
example, enable one input to affect multiple outputs or create latched outputs, etc.)
Tables 6.1 and 6.2 show details of the modes available and the switch settings required to obtain
them.
