The TBO 01 (Transistor BLOCK Output) is a BLOCK type module designed to set and visualize 16 optocoupled outputs, open collector transistor type, managed by as many TTL digital lines,that came into the module.
The inputs and power supply of TTL section are connected to a standard 20 pins I/O ABACO® connector allowing to interface the several grifo® cards, provided of at least 16 TTL output lines, like GPC® 150, GPC® 552, GPC® 15R, GPC® 188F, PIO 01, IPC 52, GPC® 154, GPC® 884, GPC® 323, GPC® 183, etc. The module connection with these cards is directly performed with a 20 wires flat cable, as the FLT 20+20 or FLT 26+20 accessories.
The sixteen 3 A transistor outputs are available on two 12 pins quick release screw terminal connectors, that allows a prompt interface to the external signals. Remarkable and really efficient is the protection offered by back suppression diodes on the power transistors, especially usefull in case of inductive loads: to take advantages from this feature it is sufficient the connection of positive supply voltage of the loads always on the described connectors.
The typical applications of the module are all the on/off driving of small and medium power devices (electric valves, power relays, signal buffers, electric locks, etc.) through comfortable and inexpensive TTL I/O lines, without using dedicated digital cards.
The board features red LEDs that provide the user a visual feed back about the status of the 16 signals of the TBO 01 module.
TBO 01 is delivered with a plastic mount for DIN 46277-1 and DIN 46277-3 rails and it doesn't require any software management.
