The Yokogawa 701870 Logic Input Module is used with the DL708, DL708E and DL716 mainframes. Specifications. Number of input points: 16 (8 bits x 2). Maximum sample rate: 10 MS/s, except the response rate depends on the response time of the logic probe. Specifications with High-Speed Logic Probe (700986). Number of input points: 8. Input format: Non-isolated (the earth of each bit are common, the earth of the logic module and the earth of each bit are common). Maximum input voltage (At 1 kHz or less): 42 V (DC+ACpeak)(CAT I and CAT II, 30 Vrms), across probe tip and earth. Response time: 1 ms or less. Input impedance: 100 k-ohm or more. Threshold level approx: 1.4 V. Specifications with Isolation Logic Probe (700987). Number of input points: 8. Input format: Isolated (all bits are isolated). Maximum input voltage (across H and L of each bit): 250 Vrms (CAT I and II). Response time: During DC input: within 1 ms, During AC input: within 20 ms. Input impedance: approx. 100 k-ohm. Threshold level: During DC input: 6 VDC ± 50% (Hi level: 10 to 250 VDC, Lo level: 0 to 3 VDC), During AC input: 50 VAC ± 50% (Hi level: 80 to 250 VDC, Lo level: 0 to 20 VAC).
