OCB001 Open Collector Interface Board Product data Features • • • • Single-ended inputs, open collector outputs Small size, easy to connect Compatible to ASSIST Evaluation & Programming Tool Suitable for development and for series production Fig 1 Open Collector Board. The Open Collector Interface Board has the following functions: - Conversion of single-ended 5V TTL or CMOS encoder signals to NPN or PNP open collector signals - Configuration and/or programming of the encoder via the ASSIST Interface Board Encoder Power The three ways to power the encoder are explained below. Encoder power from Open collector: put the Encoder Power jumper in place. Do not connect the ASSIST Board. Encoder power from ASSIST Board: remove the Encoder Power jumper, so that the open collector power supply may be connected or not. Configure the encoder using the ASSIST Board, then switch to open collector power: 1) Remove the Encoder Power Jumper 2) Connect the open collector connections, including supply pin 1 (Fig. 3) 3) Connect the ASSIST Board 4) Start the ASSIST software and configure the encoder 5) In the ASSIST software go to the evaluation window and start the encoder (the encoder is now powered by the ASSIST Board) 6) Put the Encoder Power jumper in place (the encoder is now powered by two sources with the same voltage) 7) Disconnect the ASSIST Board connector (the encoder is now powered by the open collector supply voltage) Fig 2 Open Collector Board (1) connected to ASSIST Interface Board (2), which is connected via USB cable (3) to a PC with ASSIST software. The open collector outputs (4) are available on the green terminal block. In/outputs The input signals may be on different pins of the Encoder connector and are selected in Table 1. The output type may be NPN or PNP and is selected in Table 2. Connectors The board can be ordered with or without connectors according to Table 3. If ordered without connectors, the cables can be soldered directly to the board, resulting in a low profile-height.
