Product Description

The Isolated Digital Input Terminal Board IS200TICIH1A was designed to be used with the VCCC board. The TICI board was designed to function in an equivalent manner to the TBCI board. This unit is typically used to provide voltage detection and has the ability to detect voltages across switches, relay circuits, and fuses. 

As previously mentioned the TICI board is nearly equivalent to the TBCI board save for a few features that the TICI is included with but the TBCI board is not. Some of which are the input of hardware filtering and input voltage ranges. The main hardware filtering inputs are differing time delays regarding the AC and DC applications. Both applications have a nominal time delay of fifteen milliseconds. The DC applications allow for a range of eight milliseconds whereas the AC applications allow for a range of thirteen milliseconds. One note regarding the ranges is they can either be less than or greater than fifteen as long as it is in the range of the chosen application. The IS200TICIH1A board also has input voltages that the TBCI board does not have, one of which is as follows: 190 to 264 VRMs with a nominal of 230 VRMS, operating at 47-63 Hz, with a potential detection threshold in the range of 35 to 76 VAC. 

The TICI board has clearance and creepage restrictions that must be taken into account when operating the model with applications operating at 230 VRMS. When NEMA requirements are being met the creepage/clearance should be at 230 volts on a single phase.
