4 Channel Analogue Input Module<br />
Zirconia probe input<br />
9-6<br />
The ../mV3/HiZ1 variant allows direct connection of a high impedance source such<br />
as an oxygen probe channel 1 should be set on the 2V range (Range_2). All other<br />
inputs are millivolt level.<br />
Frequency inputs<br />
The ../V2/FV2 variant supports frequncy inputs in the range 0-10kHz. Typical<br />
sources include tachogenerators and low speed encoders. Channels 1 and 3 support<br />
frequency inputs. All other channels are process level voltage inputs.<br />

Filter earth connections and signal screens<br />
Each channel is fitted with an LC input filter to provide rejection of high frequency<br />
noise spikes on the input signal. The return for this filter is connected to earth by<br />
means of a spring clip fitted to the rack pcb <strong>guide</strong> and the rack earth connection.<br />
