About
The Trig-Tek™ 260B Multi-Function Unit is designed for applications requiring up
to 80 channels of digital I/O and for observing and/or recording 16 to 64 channels
of pressure or temperature.
Product Information
The 260B consists of a motherboard that connects up to four daughterboards to the IP 1553 serial bus. Each of the modules has 16 pressure or temperature channels, a frequency counter, 12 TTL digital input channels, eight TTL output channels, and four open-drain out- puts with 2 A current capability. Each module has both nonvolatile mem- ory to store zero and gain coefficients as required to calibrate the channels and an on-board Digital-to-Analog (D/A) converter to generate accurate DC voltages for cali- bration. The modules include an RS232 bus for updating the flash to install new firmware changes. The serial data from the four modules is time division multiplexed, assembled, and delivered to the bus with a 60 updates/s rate.
