U7844 - Four channel data logger with pulse and two-state inputs
This model includes four inputs. Two of them can function as counters, and all four inputs can function as binary inputs. Both counter and binary inputs serve to monitor voltage signals or signals coming from   voltage-free contact. The binary input changes are registered immediately, irrespectively of the recording interval setting. To safe record the input status, the signal must be present for at least 1 s. Binary inputs can capture connected/disconnected voltage status. The counter states are recorded according to the set Record interval. Input signals are connected to a connecting block. The device’s ingress protection is IP 20. Due to its low ingress protection the device is not suitable for using in dusty rooms or rooms exposed to water ingress. The maximum length of the input wires should not exceed 30 m. It is recommended to use shielded cables. The battery in the device cannot be charged.

Optional input configurations:
• 2 x counter + 2 x binary input
• 1 x counter + 3 x binary input
• 4 x binary input
