METSO IOP331 181207 Digital common inputs

• These modules feature 16 digital common inputs. 48 Vdc common input; 16 channelsC Individual red front-panel LEDs provide the input status indication for each channel. A green LED, labeled Active at the bottom of the module front panel, is on when system power is present and the module is communicating with the DPU. This LED blinks on and off when the module is not being.

• The following is a simplified sketch of the circuit for one channel. The signal-conditioning block provides filtering, current limiting circuit, and an input threshold. It also includes the input status LED. The optical isolator provides isolation between the field circuits and the logic circuits. The input status is buffered and latched in the I/O bus interface circuit. The data is presented to the I/O bus as a 16-bit word when the module is scanned by the DPU. A watchdog timer in the I/O bus interface circuit controls the operation of the active LED, causing it to blink when the module is not scanned for 0.7 seconds.
