Description
The BRAF185 is uniquely designed for applications requiring process signal ramping and pulse accumulation. Such applications include motor start-up and speed control or many applications requiring time base manipulation. Ramping options include up, down or up/down and stair case control of process signal outputs over an adjustable time base. Pulse accumulation options include up, down or up/down step control of process signal outputs. All timing and accumulation tasks are performed by a microprocessor. Inputs available included voltage free contacts or external source pulses. Inputs are indicated by 3mm green LED to verify proper input wiring. Time base (Period) adjustments are adjustable via front accessible 15-turn trim potentiometers that can be externally mounted on request. External mounted potentiometers also allow for non-standard logarithmic requirements. Final calibration is trimmed using the front accessible ‘offs’ and ‘span’ 15-turn trim adjustments. Output signal is indicated by the 5mm green LED on front, which gives a clear indication of module function, presence of signal, and output loop closed (current outputs only). Various power supply choices are available varying from 415Vac down to 8Vdc all provide power isolation.
