The parameters of the TRICONEX 2481 are as follows:

Number of ports: 8
Addressing mode: The eight ports can be addressed on 8-bit, 16-bit, or 32-bit boundaries. A CSR can be addressed on an 8-bit boundary. 13 jumpers provide infinitely short data input/output address mapping options
Differential signal input characteristics: common-mode input voltage ranges from -30 to +66V. The input sensitivity is ±100mV in a common model range of -7 to +12V. The high input impedance is 33 kω
Single-ended signal input characteristics: High input impedance is 33kΩ
Threshold accuracy: The threshold accuracy of the entire system is 1%

The TRICONEX 2481 features the following:

Multi-port design: With 8 ports, these ports can be addressed on 8-bit, 16-bit or 32-bit boundaries, providing flexible address mapping options.
Differential signal input characteristics: Common-mode input voltage ranges from -30 to +66V. The input sensitivity is ±100mV in a common model range of -7 to +12V. In addition, it has a high input impedance (33 kω).
Single-ended signal input characteristics: Also with high input impedance (33kΩ).
High precision threshold: The threshold accuracy of the entire system is 1%.
