Technical Specifications
Analog Input Characteristics
The TM2AMM6HT offers 4 non-differential analog inputs. These inputs support high-level voltage and current signals. Specifically, they accept 0-10V voltage and 4-20mA current. The permissible continuous overload is 13V for voltage inputs and 40mA for current inputs. The input impedance is >= 1 Ohm for voltage and <= 250 MOhm for current. The acquisition period is 16 ms per channel plus one controller cycle time. Consequently, the module delivers reliable and stable input readings.
Analog Output Characteristics
The TM2AMM6HT provides 2 analog outputs. These outputs support both voltage (0-10V) and current (4-20mA) types. The output resolution is 12 bits. The load impedance must be >= 2000 Ohm for voltage outputs and <= 300 Ohm for current outputs. The stabilization time is 20 ms. The conversion time is 20 ms plus one controller cycle time. The output error is +/- 1% of full scale. Therefore, the outputs deliver consistent and dependable analog signals to connected field devices.
Resolution and Accuracy
The TM2AMM6HT uses a 12-bit analog-to-digital and digital-to-analog converter. The LSB value is 2.5 mV for voltage and 4 µA for current. The measurement error is +/- 0.5% of full scale at 25°C for both voltage and current. The repeat accuracy is +/- 0.5% FS for inputs and +/- 1% FS for outputs. The non-linearity is +/- 0.4% FS for both current and voltage. The total error is +/- 1.5% FS. The temperature coefficient is +/- 0.02% FS/°C. These specifications ensure precise analog signal processing.
Electrical Insulation and Protection
The TM2AMM6HT features reliable isolation between channels and the internal logic. It uses a photocoupler for this purpose. The dielectric strength is 1500V between I/O and the external supply circuit, and 800V between I/O channels. This isolation protects the controller from electrical noise. The crosstalk is <= 2 LSB. The output ripple is <= 1 LSB. These features ensure signal integrity in noisy industrial environments.
Power Supply Requirements
The TM2AMM6HT requires an external 24V DC power supply. The supply voltage limits are 19.2 to 30V. The rated supply voltage is 24V DC. The module consumes 60 mA from the 5V DC internal supply and 80 mA from the 24V DC external supply. Therefore, it draws minimal power from your control system. This low power consumption reduces overall energy costs.
