Trusted 40 Channel Analogue or Digital Output FTA
The Trusted® 40 Channel Analogue Output or Digital Output Field Termination Assembly (FTA) is designed to act as the main interface between the Trusted Triple Modular Redundant (TMR) 24 Vdc Digital Output Module T8451, Trusted Triple Modular Redundant (TMR) 24/48 Vdc Digital Output Module T84611 or Trusted TMR Analogue Output Module T8480 and the field device.
Trusted 40 Channel Analogue or Digital Output FTA Features
• 40 output channels per FTA.
• Industry standard field device connections (2-wire).
• Standard DIN rail compatibility.
• Screw clamp terminals on both field and power.
• Simple installation and connection.
• 24 Vdc operation.
• SmartSlot connection for ‘one to many’ hot replacement of output modules.
• Five isolated groups of eight channels.
• On-board LED indication of field power supply.
• Field terminal wire size allowance 12 AWG to 28 AWG.
Recommended proof test methods
Calibration check procedure:24V DC digital outputs
Step A - Set the current to the AI channel 4 mA, verify that the input value is in the range -41 to +41 counts.
Step B - Set the current to the AI channel 12 mA, verify that the input value is in the range 2007 to 2089 counts.
Step C - Set the current to the AI channel 20 mA, verify that the input value is in the range 4055 to 4137 counts.
Step D – Return to Specific Method.
This test is required for all 24V DC DO modules or DC powered NO Contact where Normally De-energized (Energize to Trip) channels (T8850 when used with the T8451, T8461, or T8891 when used with the T8842) are used for Safety-Related Outputs used where the Proof Test frequency >> frequency of Demands. The purpose of this test is to verify that the diodes used for OR’ing the two Field Power sources are not Open circuit, therefore does not constitute a potential undetected dangerous failure. The method described here is the recommended method to verify that neither of the diodes used to OR the 24V DC field supply to a specific T8850 FTA, or the DC supply feeding NO Contact outputs is open circuit. It is assumed that this methodology will be incorporated into a Proof Test procedure that includes other elements of Proof Testing and general proof test requirements as defined in IEC61511.
Method:
Step 1 - If performing this test on a live system, it may be necessary to employ a method external to the Trusted logic solver to mechanically or electrically force any Normally Energized (De Energize to Trip) outputs associated with final elements on the FTA under test into their normal operating state. If not, proceed to Step 2.
Step 2 – Turn off the ‘A’ field supply at an appropriate isolation or termination point and verify that the diode related to ‘B’ supply is correctly providing 24V DC to each power group on the FTA under test.
NOTE: Although strictly NOT required from a Proof Test perspective, a secondary test can be performed while the ‘A’ Power source is turned off (disconnected) to verify that the diode associated with the ‘A’ supply is not ‘Short Circuit’. With 1k ohm resistor connected in series with the meter, measure the current (in mA) from the supply side of the diode to 0V and the current should be << 24 mA if the diode is correctly preventing backfeed of the ‘B’ supply (there will be a small leakage current, so it may not be 0 mA).
Step 3 – Return the ‘A’ field supply into service.
Step 4 – Turn off the ‘B’ field supply at an appropriate isolation or termination point and verify that the diode related to ‘A’ supply is correctly providing 24V DC to each power group on the FTA under test.
