2. Installation
2.1. Module Insertion/Removal
CAUTION:
The module contains static sensitive parts. Static handling precautions must be observed. Specifically
ensure that exposed connector pins ARE NOT TOUCHED. Under no circumstances should the
module housing BE REMOVED.
Before installation, visually inspect the module for damage. Ensure that the module housing appears
undamaged and inspect the I/O connector at the back of the module for bent pins. If the module
appears damaged or any pins are bent, do not install the module. Do not try to straighten bent pins.
Return the module for replacement.
Ensure that the module is of the correct type.
Record the module type, revision and serial number of the module before installation.
To install the module:
1. Ensure that the field cable assembly is installed and correctly located.
2. If I/O module keys are used, verify that all keys are installed in the correct positions and
properly seated in their slots.
3. Release the ejector tabs on the module using the release key. Ensure that the ejector tabs
are fully open.
4. Holding the ejectors, carefully insert the module into the intended slot.
5. Push the module fully home by pressing on the top and bottom of the module fascia.
Close the module ejectors, ensuring that they click into their locked position.
The module should mount into the chassis with a minimum of resistance. If the module does not
mount easily, do not force it. Remove the module and check it for bent or damaged pins. If the pins
have not been damaged, try reinstalling the module.
2.2. Cable Selection
I/O cables suitable for use with the Trusted TM TMR 24/48V dc Digital Output Module are detailed in the
following Product Descriptions.
1. PD-TC200 – Trusted TM I/O Companion Slot Cables
2. PD-TC500 – Trusted TM I/O SmartSlot Cables
The Product Descriptions detailed above also detail the types of Field Termination Assembly (FTA) or
Versatile Field termination Assembly (VFTA) which may be used with type of module.
Custom length multi-core FTA cables are 0.5mm 2 with a resistance of 40P/km. eg a 50m cable will
have 4P loop impedance at 0.5A, this equates to a 2Vdc volt drop.
2.3. Termination
Unused outputs should be commanded off in the application and wired through a 10K 0.5W resistor to
zero volts.
