Rockwell Automation TDI16AIA 16-Channel Digital Input Termination Card 24Vdc - Manual (Page 2)

2 TAI16AIA October 2005 – Issue 3
Triguard SC300E
SPECIFICATION
Model TDI16AIA
Power Supply inputs Has two separate connectors (FS1and FS2)
for redundant dc power supplies. The positive
supplies feed a common bus via auctioneering
diodes. When auctioneering takes place
outside the card, the required power may be
supplied via a single connector.
No. of digital input channels 16
Nominal field supply voltage 24Vdc
Maximum field supply voltage 33Vdc
Current rating 50mA per channel.
NOTE: In normal operation when used with a
Digital Input Module having a 10k ohm input
resistance, the current in each channel will be
2.4mA with 24V field supply.
Fuse in each positive line to field 1A, fast acting, indicating
Chassis cable connector 34 way DIN41612
Field cable connector Screw terminals to suit 2.5mm 2 wire (16AWG)
Fuse blown indication Local: Fuse blown LED (one per card)
Remote: Fuse blown alarm output (PL1) – can
be connected to Fuse blown LED on Power
Distribution Panel (PDD24).
Transient suppression A transient suppressor device between each
field return line and a common 0V bus clamps
the field return line voltage (with respect to 0V
common) as follows:
+37Vdc to +43Vdc @ 1mA (maximum for
continuous overload)
+70Vdc @ 69A maximum peak pulse current
for 8ms to 20ms
Safety ground terminal TS1 M3 threaded bush provision for a ring terminal.
Allows the common 0V supply bus to be
grounded via a 10k ohm resistor. Prevents the
channels from floating if the card is
disconnected from the chassis
